Unlike other financial pros who recently started using the social micro-blogging platform, Ackman has kept his Twitter page sparse — lacking a headshot and a bio. And so far, it has zero tweets.

It is “to be determined” whether Ackman will tweet, a source told The Post.

Nevertheless, it hasn’t stopped the silver-haired hedgie from quickly amassing more than 2,800 followers as the Twitterati sit in hopeful anticipation of Ackman’s musings.

Ackman so far follows 46 accounts, representing a mix of politicians, news organizations and fellow executives. Being a registered Twitter user makes it easier to access the tweeting history of others — something Ackman will likely do when he is busy not tweeting.

A list of other Wall Street pros who have recently started tweeting includes Goldman Sachs CEO Lloyd Blankfein, who did so six years after joining the social media company, Bridgewater Associates’ Ray Dalio and DoubleLine Capital’s Jeffrey Gundlach.
